DESCRIPTION
The
µ
A741 is a high performance operational amplifier with high
open-loop gain, internal compensation, high common mode range
and exceptional temperature stability. The
µ
A741 is
short-circuit-protected and allows for nulling of offset voltage.
FEATURES
·
Internal frequency compensation
·
Short circuit protection
